The concept of relationship self-regulation (RSR) has been shown to be related to relationship satisfaction, yet the differences in RSR ability based on couple type have yet to be examined. This study compared first married, remarried, and cohabiting individuals on their self-reported ability to implement RSR in their relationship, along with their report of satisfaction, positive communication, and negative communication in their relationships. Data was derived from 6,591 participants who were part of the RELATionship Evaluation (RELATE) questionnaire data set. Multiple Analysis of Covariance (MANCOVA) statistics were used, and results showed that while mean differences in RSR were small across couple types, remarrieds reported significantly lower RSR levels than any other group, while first marrieds reported significantly higher RSR levels than any other group. Implications for relationship education programs and couple therapy are discussed with particular emphasis placed on ensuring that RSR related programs are being delivered to remarried individuals and couples.
